Building Your ConstraintLayout Toolbox
summary
Shows a concrete movie-detail layout and pulls out actual ConstraintLayout tools used to solve real problems: using match_constraint (0dp) plus constraintDimensionRatio to keep posters square, baseline alignment for text, handling impossible constraints with bias, and toggling behavior via barriers and guidelines and groups. Recommends constrainedWidth/constrainedHeight for dynamic content. Demonstrates Flow as a Flow (flexbox-like) replacement for a custom view group (used to implement Slack‑style reactions), claiming this toolbox covers roughly 80–90% of everyday layouts.
